Desire to try tubes


So I am new to this have no audio contacts, and low budget it seems based on reading forum. I inherited my brothers Heresy I’s (and LP /CD collection) two years ago and started my journey. First bought a Rega P3 and Rega Fono stage running with existing 20 yo Denon 5.1. Then upgraded the Hereseys from Crites with crossovers and new tweeters (46 yo units). Months later after research and savings bought Stellar GCD and Stellar S 300 amp along with Syzygy SLF 870 sub from Underwoodwally. Nice! Next Marantz 6006 CD as transport and Underwood Emerald Physics and Core Power gold power cords and speaker cables. As able Audio Quest entry connects for all. Each move improved sound. Added a Bluesound node 2i as well only listening to Pandora though. I have no reference to options as I’ve only owned Hereseys and never heard a tube amp in a home and am very curious if a tube pre-amp would be a big plus? If I tried one could muster up to 5k. Just looking for the best sound quality I can afford.
Room is 14.6 x 14.10 x sloped ceiling 8-13’ with 5’ flat section at 13.

Heresy are efficient so Shindo would be worth checking out, a few of my friends have Klipsch Scalas and Horns paired with Shindo and it’s gorgeous. Hard to find but the Appetite is a 15w integrated.
I use a Schiit Freya (original version) with NOS GE 6SN7GTB tubes driving a Dennis Had Inspire Firebottle HO ("high output" at 10 to 17 watts depending on tubes selected) SE amp. Total cost for both was originally around 2 grand (the Had amp was 2 months old bought from the original owner). This combo is the best sounding amp/preamp rig I've owned, and better than any I've actually heard...into Klipsch Heresy IIIs...great "budget" stuff with world class sound.
klipsch’s have their own sound signature for sure... if you like their sound then it is certainly a major benefit that they afford the use of some very very very fine sounding low powered single ended tube amps - amps that cannot be used with many other good speakers with lower efficiency
+1, for the integrated thoughts.      + another 1 for the VTL integrated, though; you’ll never need that much power.             Excellent construction, wonderful performance, great customer service and made in the USA.      ie: https://www.hifishark.com/model/vtl-it-85
